Writing in her book ‘The Coregasm Workout’, Herbenick claims that the gym-related climax is a result of working the abdominal muscles – and not because gym shorts can rub against your genitals during a workout, getting you a little bit under the collar.

Supporting the claims, Herbenick also cited a theory which outlined the intensity of the gym induced orgasm – describing it as being higher than that achieved by masturbating, but less intense than sexual intercourse.

And as for how to achieve it, Herbenick added that a gym goer must work their muscles to the point of fatigue – continuing exercise when the first pangs of excitement are felt.
